New P-10C not consistently chambering when the slide is open

[Walt Sherrill]

...We are taught not to use the slide stop because over time the corners round on our range guns and they won't stay open.

I've heard of THIS particular issue, but have only seen it once, with a less-expensive gun that was many years old. 

If it happens, I suspect that the notch on the slide can be touched up so that the slide will still locks open, as doing so won't greatly affect the slide position when it's locked open after the adjustment.  I don't remember hearing of anyone doing that sort of adjustment (probably with a fine file) but if wear does affect the shape of the notch, I also suspect it will work.

As I've noted before, the U.S. Department of Defense now teaches those going through handgun training to use the stop/release lever.  This change in training was introduced because of issues encountered in Iraq and Afghanistan, where slides weren't going fully into battery under combat conditions, which meant the shooter had to diagnose and either slam the slide closed or rack the slide and lose a round - which runs the risk of having to do it again.

The hand-over method will work with most guns, but when used with the Beretta 92/M9  (or a similar Taurus), the hand-over technique can  decock the weapon. That doesn't disable the weapon, but it can slow things down a bit and give the shooter a heavier (i.e. full DA) trigger pull than expected.

The problem with using the stop/release lever is that it can require, depending on the shooter, the use of the off-hand, but there are very effective and very easily-learned -- and suprisingly rapid -- ways to do that.

My new 10C will auto forward on a full mag 100% but I admit to be a mag slammer. It will do it mostly on a mag less than full mag but not as consistently.

At first I found it quite disconcerting, mostly because I didnt expect it, but now I look at it as a feature. It locks back religiously on empty mags so I think I will just leave it as is. Unless someone tells me its dangerous or that this is actually a flaw in the gun I am reluctant to contact CZ. Gun works and its fun as hell to shot.

My 10-C auto forwards all the time. I too thought it was part of the features. It has failed to load a round a few times out of maybe 100 reloads. More often than not I usually have my thumb on the slide release anyway ready to drop the slide once the mag is in. When I have partial pressure on the slide release and get the mag in forcefully it usually does what it's supposed to do without incident.
